Finding Someone in Custody in Flagstaff
A person kept in custody after an arrest in Flagstaff is held at the county jail, run by the Coconino County Sheriff's Office, whichever agency made the arrest.
SearchSystems opened and checked the jail page of the Coconino County Sheriff's Office at coconino.az.gov/325/Sheriff (page title: Coconino County Sheriff's Office | Coconino), phone 928-774-4523, a site that blocks automated checks (HTTP 403), so open it in a browser.
That page is the office's jail information page rather than a roster, so a search for a particular person goes through the office at 928-774-4523.
